Executable = "run.sh";
Arguments = "";
StdOutput = "std.out";
StdError = "std.err";
InputSandbox = {"run.sh"};
OutputSandbox = {"std.out", "std.err"};
Requirements =  RegExp("ce64.ipb.ac.rs*",other.GlueCEUniqueID);

5. Make a run.sh file with following content

#Downloading source code from SE
lcg-cp lfn:/grid/aegis/power/src.tgz 'src.tgz'

#Extract code 
tar xvzf src.tgz

#Compile C file

gcc hello.c -o hello

#Execute hello program

./hello >> output

#Make tgz arhive of output 
tar cvzf output.tgz output

#Uploads output to SE
lcg-cr -l lfn:/grid/aegis/nikola/hello.SE/output.tgz file:`pwd`/output.tgz
lcg-cr -l lfn:/grid/aegis/nikola/hello.SE/std.err file:`pwd`/std.err

6. Creating VOMS proxy:

[ngrkic@ui hello.SE]$ voms-proxy-init -voms aegis
